Nowadays, we do not imagine ourselves without a permanent connection to the World Wide Web. Therefore, all kinds of gadgets are constantly connected via Wi-Fi with the nearest access point – at home, at work, in the subway. And even if there are no repeaters available within the range of the wireless module, it still continues to work, scanning the Wi-Fi range for fast connection.
Around the clock wasting energy and radiating microwaves node smartphone worries many users. Some believe that it should be turned off at night, others act more radically, including the option only for the duration of work on the network. Which approach can be called more true? Let’s try to figure it out.
Of course, the work of this, like any other phone modules, requires energy. But not so much compared to such demanding components as the screen or processor. Therefore, if you turn off Wi-Fi at night in order to save, it will not give special results.
Work with software updates
If your phone is connected to the Internet via Wi-Fi, in those moments when it is not in use, most likely, updates of the operating system and applications will be downloaded and installed. This is a rather expensive operation for a battery – at such moments the device electronics “plow” to the maximum. If you turn off Wi-Fi at night, you will be left without updates. There is nothing good about it – they are convenient and useful from a security point of view.
The harm of electromagnetic radiation from the phone in general and Wi-Fi in particular remains the subject of discussion. There is evidence that gigahertz radio waves can cause headache, sleep disorders and even cancer. However, scientists cannot say for sure about this – insufficiently reliable experimental results.
However, if you intend to save your health from harmful radiation by turning off Wi-Fi, there is no special sense in this. First, the transmitter module will remain on. The power of the radio waves emitted by it is higher, and in addition, Internet traffic will go through it. Secondly, if you already fight for the cleanliness of the house from microwaves, it makes sense to turn off the Wi-Fi router. It is unlikely that your neighbors do the same. Therefore, from the ubiquitous radio waves can not escape.
Summing up, I would like to draw your attention to the significant successes achieved in electronics. Modern gadgets are designed so optimally that disabling any of their parts, including Wi-Fi, is impractical.
